Certain exemplary embodiments are described below in greater detail withreference to the accompanying drawings.

In the following description, like drawing reference numerals are usedfor the like elements, even in different drawings. The matters definedin the description, such as detailed construction and elements, areprovided to assist in a comprehensive understanding of the exemplaryembodiments described herein. However, other exemplary embodiments canbe practiced without those specifically defined matters. Also,well-known functions or constructions are not described in detail sincethey would obscure the application with unnecessary detail.

FIGS. 1A and 1B are diagrams illustrating implementation examples of anaudio-visual system, according to an exemplary embodiment.

Referring to FIG. 1A, an audio-visual system 1000 may include anaudio-visual device 100, a housing 10, and a lifting device (not shown).

The audio-visual device 100 may be configured to provide functions of avisual device for displaying images and an audio device for outputtingand recording sounds. For example, the audio-visual device 100 may beused as a visual device, such as, a TV, a monitor, and the like, or maybe used as an audio device for reproducing, outputting, or recordingdiverse formats of sound sources. In this case, a display of theaudio-visual device 100 may be formed as a flat panel in a roughrectangular shape, like a common Liquid Crystal Display (LCD) TV orOrganic Light-Emitting Diode (OLED) TV. Further, the display of theaudio-visual device 100 may be formed as a curved-surface panel withcertain curvature. The following exemplary embodiments will be describedwith the assumption that a display 110 is formed in a flat panel shape.

The housing 10 includes an internal space for storing the audio-visualdevice 100 and an opening 11 on an upper end. Accordingly, the housing10 is formed to correspond to a shape of the audio-visual device 100. Asillustrated in FIG. 1B, the audio-visual device 100 may selectivelyprotrude from an upper side of the housing 10 through the opening 11formed on the upper end of the housing 10. The housing 10 may berealized such that the audio-visual system 1000 including theaudio-visual device 100 functions as furniture for storage and interiordecoration. Accordingly, an external surface of the housing 10 may bedesigned so as to allow various decorations and storage.

To be specific, a couple of support stands 13 for supporting the housing10 with respect to a floor surface are provided on both lateral surfacesof the housing 10. The couple of support stands 13 are installed suchthat a bottom surface of the housing 10 is spaced apart from the floorsurface. In this case, the floor surface may include a floor of a placewhere the housing 10 is installed, for example, a room, a living room, abed room, an office, a public space, or the like.

A plurality of holes 15 a are formed on a front surface 15 of thehousing 10. The plurality of holes 15 a are formed to fix accessories31, 32, 33, 34. The accessories 31, 32, 33, 34 are fixed by means of theplurality of holes 15 a on the front surface 15 of the housing 10 so asto support objects, for example, a book, with respect to the housing 10.By way of example, as illustrated in FIG. 1B, the accessory 31 may beformed in a flat-panel shape to be fixed by using one or more of theplurality of holes 15 a. The accessories 32, 33 may be formed in a rodshape to be fixed to one or more of the plurality of holes 15 a throughits one end. The accessory 34 may be formed in a rough bracket shape tobe fixed to one or more of the plurality of holes 15 a through its bothends. An accessory may be formed in a rough ‘L’ shape to be fixed to oneor more of the plurality of holes 15 a through its one end. Theaccessories 31, 32, 33, 34 in FIG. 1B are only examples for illustrativepurpose, and the shape of the accessory is not limited thereto.

In the same manner as on the front surface 15 of the housing 10, aplurality of holes may additionally or alternatively be formed on a rearsurface 16 of the housing 10, and various accessories may be fixed tothe plurality of holes on the rear surface 16 of the housing 10.

Meanwhile, at least one speaker for outputting sound of a contentreproduced in the audio-visual device 100 may be installed around thebottom surface in the housing 10. As an example, two speakers may beinstalled inside the housing 10 separately from the audio-visual device100. The sounds output from the two speakers may be transmitted to anoutside through the plurality of holes 15 a on the front surface 15 ofthe housing 10 and/or the plurality of holes on the rear surface 16 ofthe housing 10. In this case, the housing 10 may expand a volume of asound box of the speakers, thereby improving sound quality. Further, anopening corresponding to the speaker(s) on the front surface 15 of thehousing 10 may be formed such that a front surface of the speaker(s) isexposed to the outside. The at least one speaker may additionally oralternatively be installed outside the housing 10.

As described above, it is able to achieve an effect of using a speakerlarger than an embedded speaker of the audio-visual device 100 byinstalling at least one speaker separately from the audio-visual device100. Accordingly, the audio-visual device 100 may provide good soundquality when used as the audio device. Needless to say, a speaker may bealso embedded in the audio-visual device 100.

A lifting device (FIG. 2B, 200) is configured to expose the audio-visualdevice 100 or store the audio-visual device 100 inside the housing 10through the upper end of the housing 10.

The lifting device (200) is installed on a lower part of theaudio-visual device 100 in the housing 10 and may be realized as alifting unit (210) for vertically moving the audio-visual device 100with respect to the housing 10. That is, the lifting device (200) makesthe audio-visual device 100 protrude outside the housing 10 through theopening 11 on the upper end of the housing 10 such that the display 110is exposed and also makes the protruded audio-visual device 100 descendso as to be stored in the housing 10. As the audio-visual device 100 isstored in the housing 10, the display 110 of the audio-visual device 100is protected by the housing 10.

The lifting device (200) may be configured to locate the audio-visualdevice 100 at at least two different heights. For example, the liftingdevice (200) may be configured to move the audio-visual device 100between a first position where the audio-visual device 100 is entirelystored in the housing 10 so as not to be exposed to the outside of thehousing 10 and a second position where at least a part of theaudio-visual device 100 is exposed to the outside of the housing 10. Inthis case, the second position may include a position where the display110 of the audio-visual device 100 is entirely exposed to the outsideand/or a position where only a part of the display 110 of theaudio-visual device 100 is exposed to the outside.

For doing this, the lifting device (200) may include a lifting unit(210) configured to be installed on a lower part of the display 110 ofthe audio-visual device 100 to make the display 110 protrude through theupper end of the housing 10 and a driving unit (220) configured to drivethe lifting unit (210). In this case, the driving unit (220) may beconfigured to drive the lifting unit (210) by rotation of a motor. Forexample, the number of rotations of the motor may be adjusted tocorrespond to the height of the audio-visual device 100.

FIG. 2A is a diagram illustrating a structure of an audio-visual device,according to an exemplary embodiment.

Referring to FIG. 2A, an audio-visual device 100 includes the display110, a speaker 120, and a processor 130.

The audio-visual device 100 may be realized as a smart TV, a monitor, orthe like, but not limited thereto. The audio-visual device 100 may berealized as various types of devices providing a display function, forexample, a Large Format Display (LFD), a digital signage, a DigitalInformation Display (DID), a video wall, a projector display, and so on.

The display 110 may display diverse content screens that may be providedthrough the audio-visual device 100. In this case, the content screensmay include various contents including images, moving images, text,music, or the like, an application execution screen including variouscontents, a Graphic User Interface (GUI) screen, and so on.

The display 110 may be realized as diverse types of displays, such as,LCD, OLED, Liquid Crystal on Silicon (LCoS), Digital Light Processing(DLP), or the like. Further, the display 110 may be realized as atransparent display with transparent materials to display information.In some cases, the display 110 may be realized as a touch screen thatforms a mutual layer structure with a touch pad. The display 110 may beused as a User Interface (UI), as well as an output device, in thiscase.

The at least one speaker 120 is installed on at least one side of thedisplay 110. The speaker 120 converts electric pulses into sound waves.The speaker 120 may be realized as a dynamic type classified byprinciples and methods for converting electronic signals into soundwaves, but not limited thereto. That is, the speaker 120 may be realizedas an electrostatic type, a dielectric type, a magneto striction type,or the like. Further, the speaker 120 may be realized as a multi-waytype that divides a register of a frequency band into a low register, amiddle register, and a high register and assigns each register to aproper speaker.

The processor 130 may control overall operations of the audio-visualsystem 1000 including the audio-visual device 100. The processor 130 mayinclude one or more components from among a Central Processing Unit(CPU), a controller, an Application Processor (AP), a CommunicationProcessor (CP), and an ARM processor.

The processor 130 may control the audio-visual system 1000 to operate ina first mode for outputting a media art content while the display 110 isstored in the housing 10 in response to a first event, operate in asecond mode for outputting an audio content through the speaker 120while a part of the display 110 is exposed to the outside through theupper end of the housing 10 in response a second event, and operate in athird mode for outputting a visual content while the entire display 110is exposed to the outside through the upper end of the housing 10 inresponse a third event.

In response to a mode being determined according to an event, theprocessor 130 may control the operation of the lifting device (200) suchthat the display 110 is exposed or is stored in a state corresponding tothe determined mode. For example, when the lifting device (200) includesthe lifting unit (210) being installed on the lower part of the display110 of the audio-visual device 100 so as to make the display 110 projectthrough the upper end of the housing 10 and the driving unit (220) fordriving the lifting unit (210) by means of the motor, the processor 130may control the driving unit (220) of the lifting device (200) such thatthe number of rotations of the motor is adjusted according to thedetermined mode.

The first to third events for executing the first to third modes may bethe events where each mode is selected by a user command. As an example,the events may include an event where a mode is selected by a remotecontrol device including a remote controller, an event where a mode isselected by a user gesture or user voice command, an event where a modeis selected by a button on the audio-visual device 100, and so on. Asanother example, a plurality of selection switches 22 for selecting aprojecting state of the audio-visual device 100 may be provided on anupper bezel area of the audio-visual device 100. The plurality ofselection switches correspond to each of a plurality of heights wherethe audio-visual device 100 may be located, respectively. Accordingly,in response to one of the plurality of selection switches being pressed,the processor 130 locates the audio-visual device 100 at a heightcorresponding to the pressed selection switch, and then a modecorresponding to the height is executed automatically.

The events are not limited to the above-described examples, and theevents may further include an event where a certain type of content isselected, an event where a predetermined time arrives, an event where anexposure degree of the audio-visual device 100 is adjusted manually, anevent where a user is recognized, and the like. As an example, theprocessor 130 may control the audio-visual system 1000 to automaticallyoperate in the first mode in response to receiving a command forselecting a media art content, automatically operate in the second modein response to receiving a command for selecting an audio content, andautomatically operate in the third mode in response to receiving acommand for selecting a visual content. As another example, when theaudio-visual device 100 is realized as a large display device, such as,the LFD or DID, the audio-visual system 1000 may operate in the firstmode or in the second mode while a user is not recognized in front ofthe audio-visual device 100 and operate in the third mode for displayinga content, such as, an advertisement or the like, when a user isrecognized in front of the audio-visual device 100. As still anotherexample, the audio-visual system 1000 may operate in the first mode fordisplaying the media art content providing appropriate illumination forsleeping during a predetermined time (for example, a bedtime from 12:00a.m. to 7:00 a.m.).

Meanwhile, according to an exemplary embodiment, a user terminal device,such as, a mobile phone, may be used as the remote control device. As anexample, the mobile phone may be triggered to provide a remote controlfunction with respect to the audio-visual system 1000 through a contactor Near Field Communication (NFC) with respect to the audio-visualsystem 1000. As another example, the mobile phone may be automaticallytriggered to provide the remote control function with respect to theaudio-visual system 1000 based on at least one of a user location, atime, and content use information. As still another example, in responseto the mode being converted, the mobile phone may be automaticallychanged such that a button that may be used on the mobile phone (forexample, a touch button) corresponds to the converted mode.

In response to the mode being determined (or executed) according to anevent, the processor 130 may automatically communicate with a sourcedevice providing content that is outputtable in the determined mode. Forexample, the processor 130 may automatically communicate with a sourcedevice providing a media art content in the first mode, automaticallycommunicate with a source device providing an audio content in thesecond mode, and automatically communicate with a source deviceproviding a visual content in the third mode. In this case, thecommunication connection may refer to all kinds of communication ablestates, for example, communication initiation, network formation, ordevice pairing between the audio-visual device 100 and a source device.As an example, device identification information on the audio-visualdevice 100 may be transmitted to the source device, and then pairingbetween the audio-visual device 100 and the source device may beperformed. As another example, in response to a predetermined eventoccurring in the audio-visual device 100, a peripheral may be searchedthrough a Digital Living Network Alliance (DLNA) method, and then thepairing may be performed such that the peripheral operates with a sourcedevice corresponding to the determined mode.

In this case, the processor 130 may display a list of contents that maybe provided by the connected source device. For example, in response toa set-top box being connected as the third mode is selected, theprocessor 130 may display an Electronic Program Guide (EPG) list. Inresponse to the mobile phone (or external server) being connected as thesecond mode is selected, the processor 130 may receive and display alist of audio contents that may be provided by the mobile phone (orexternal server). In response to a pre-stored contents being provided,the processor 130 may automatically display a list of the pre-storedcontents corresponding to each mode, needless to say.

In response to the mode being determined according to an event, theprocessor 130 may perform local dimming to at least a part of a screenarea of the display 110 based on an image size of a content output inthe determined mode. For example, in response to information on an audiocontent reproduced in the second mode being provided to only a part of ascreen area exposed to the outside of the housing 10, the processor 130may perform the local dimming to the other screen area than the exposedscreen area, that is, a screen area located inside the housing 10,thereby reducing power consumption.

In response to the mode being determined according to an event, theprocessor 130 may control the mode to be converted to an optimal outputmode where the user is able to view or listen to a content based onproperties of the content provided in the determined mode.

As an example, in response to the mode being determined according to anevent, the processor 130 may activate at least one speaker to correspondto the audio content output in the determined mode and automaticallyadjust a sound output volume to correspond to the determined mode. Forexample, an appropriate speaker and sound output volume may have beenset for each mode.

As another example, in response to the mode being determined accordingto an event, the processor 130 may automatically perform soundequalizing corresponding to the sound output in the determined mode. Forinstance, in response to the audio content being reproduced in thesecond mode, the processor 130 may automatically perform the soundequalizing corresponding to a genre of the audio content (for example, arock genre).

As another example, in response to the mode being determined accordingto an event, the processor 130 may adjust output brightness of a pixelbased on the properties of the determined mode. That is, the processor130 may decrease the pixel brightness in the first and second modes andincrease the pixel brightness in the third mode. Alternatively, theprocessor 130 may convert the output mode to a low-power mode where thepixel brightness is decreased automatically, in the first and secondmodes.

The processor 130 may change a display position or brightness of acontent according to a user command in each mode. For example, theprocessor 130 may change the display position of a media art content inthe first mode according to a user gesture command or change thebrightness of the media art content to change ambient illuminance.

The processor 130 may provide a predetermined feedback in response tomode conversation. For example, the processor 130 may provide at leastone of a visual feedback providing a predetermined image and an auditoryfeedback providing a predetermined sound. In this case, the processor130 may provide different types of feedbacks related to thecharacteristics of a converted mode. For example, the processor 130 mayprovide the visual feedback in response to the mode being converted froma certain mode to the first mode and provide the auditory feedback inresponse to the mode being converted from a certain mode to the secondmode.

In the first mode, the processor 130 may automatically communicate withan external source (for example, an external electronic device, anexternal server, or the like) providing the media art content to receivethe media art content or display the media art content pre-stored in theaudio-visual device 100 on the screen of the display 110. In this case,the operation of receiving and displaying the media art content from theexternal source may include an operation of downloading content from theexternal source and reproducing the content by the processor 130 and anoperation of receiving content reproduced in the external source (forexample, a mobile phone) in a streaming manner and displaying thecontent. In this case, in response to a resolution of the media artcontent downloaded or received from the external source in the streamingmanner being different from a resolution of the display 110, theprocessor 130 may convert a format of the content to an appropriateresolution and then display the content.

In this case, the media art content may be content selected by the userwhen the mode is selected or may be content set by default to beautomatically provided when the mode is selected. As an example, inresponse to a predetermined bedtime arriving, the processor 130 mayexecute the first mode automatically and display the media art contentfor helping with the user's sleep in order to use the media art contentas a sleeping light.

In addition, the media art content may be content including at least oneof a video and an audio. According to the setting in the first mode,only a part of the content may be provided. For example, although themedia art content is content including both the video and the audio, theprocessor 130 may reproduce only the video, except for the audio,through demultiplexing according to the setting in the first mode.

The media art content received from the external source, such as, theuser terminal device, may be content edited through an editor UIprovided by the user terminal device. As an example, the user is able toedit and generate media art content providing a pattern for helping withthe sleeping through the editor UI. In this case, the processor 130 maytransmit the information on the audio-visual device 100 (for example,the resolution or the like) to the user terminal device, and the userterminal device may provide the editor UI based on the receivedinformation. By way of example, an application for controlling theaudio-visual device 100 providing three kinds of modes according to thepresent exemplary embodiment may be installed in the user terminaldevice, and the user terminal device may control the modes of theaudio-visual device 100 through the application.

The processor 130 may change a display range automatically according toan attachment state of the accessory 31, 32, 33, 34 on the front surface15 of the housing 10. To be specific, the processor 130 may sense theattachment state of the accessory 31, 32, 33, 34 by means of a proximitysensor or the like and display the media art content in a screen areathat is not blocked by the accessory 31, 32, 33, 34, based on thesensing result.

As described above, in response to the media art content being outputwhile the audio-visual device 100 is entirely stored in the housing 10,the light emitted through the plurality of holes 15 a on the frontsurface 15 of the housing 10 may be utilized as a media object orillumination.

According to circumstances, the processor 130 may display the media artcontent by exposing a part of the display 110 to the outside of thehousing 10 in the first mode in order to provide the illuminationfunction. In this case, the processor 130 may display a single contenton the entire screen or display a content only in the exposed area.Further, the processor 130 may display different contents in the exposeddisplay area and an unexposed area.

The processor 130 may automatically communicate with an external sourceproviding an audio content (for example, an external electronic device,an external server, or the like) in the second mode to receive the audiocontent (for example, an audio file with a file extension, such as, MP3,WMA, OGG, WAV, or the like) or may reproduce the audio contentpre-stored in the audio-visual device 100. In this case, the operationof receiving and reproducing the audio content from the external sourcemay include an operation of downloading the audio content from theexternal source and reproducing the audio content by the processor 130and an operation of receiving the audio content reproduced in theexternal source (for example, a mobile phone) in the steaming manner andoutputting the audio content.
